Description

Technical Field

[0001] This utility model relates to the field of welding positioning technology, and more specifically, to an automatic welding positioning device for stainless steel profiles. Background Technology

[0002] In the welding of stainless steel profiles, precise positioning and stable fixation are crucial prerequisites for ensuring welding quality. Traditional welding positioning devices typically employ fixed-spaced support structures and a single clamping method, which are ill-suited for the rapid positioning needs of profiles with varying specifications. Furthermore, when dealing with profiles of complex shapes or varying lengths, frequent manual adjustments are required, leading to low production efficiency. In addition, existing devices have limited adjustment ranges for the welding head position, often failing to flexibly match the requirements of different welding positions. This can easily result in insufficient welding accuracy and unstable weld quality due to positioning deviations or inconvenient adjustments.

[0003] Although some improved positioning devices in the existing technology have achieved a certain degree of automated adjustment by adding a drive mechanism, they still have limitations in terms of multi-dimensional positioning coordination, profile adaptability, and welding process stability. For example, the lack of a precise correction mechanism for the lateral position of the profile makes it difficult to ensure that the profile is in a fully aligned state before welding; at the same time, the insufficient design of the guide structure of the clamping component may cause the profile to shift during the clamping process, affecting the accuracy of the welding reference.

[0004] Therefore, an automatic welding positioning device for stainless steel profiles is proposed. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automatic welding positioning device for stainless steel profiles to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic welding and positioning device for stainless steel profiles, comprising a base plate, a column on the base plate, a top plate supported at the top of the column, a first electric push rod mounted on the top plate, a lifting plate connected to the telescopic end of the first electric push rod, a second electric push rod mounted at one bottom end of the lifting plate, a first slider mounted at the end of the second electric push rod, a welding head mounted at the bottom of the first slider, an adjusting mechanism mounted on the base plate, a clamping assembly mounted on the adjusting mechanism, and a side-pushing assembly mounted on one side of the clamping assembly.

[0007] Preferably, a vertical rail is provided on one side of the column, and the vertical rail is slidably connected to one end of the lifting plate.

[0008] Preferably, a horizontal rail is installed at the bottom of the lifting plate, and the first slider is slidably connected to the horizontal rail.

[0009] Preferably, the adjusting mechanism includes a first motor, a first screw, a second screw, a slide block, and a slide rail. The first motor is mounted on a base plate, the output end of the first motor is connected to the first screw, one end of the first screw is connected to the second screw, and a slide block that is slidably connected to the slide rail is sleeved on both the first screw and the second screw.

[0010] Preferably, the side-push assembly includes a second motor, a rotating rod, a rotating plate, a fourth electric push rod, and a push plate. The second motor is mounted on one side of the slide block, and the output end of the second motor is connected to the rotating rod. The rotating plate is fixedly connected to the rotating rod, and the fourth electric push rod is mounted on the rotating plate. The extension end of the fourth electric push rod is mounted with a push plate.

[0011] Preferably, the clamping assembly includes a third electric push rod, a pressure plate, and guide rods. The third electric push rod is mounted on an L-shaped bracket on one side of the slide block. A pressure plate is installed at the telescopic end of the third electric push rod. Two guide rods that are slidably connected to the L-shaped bracket are symmetrically arranged at the top of the pressure plate.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. The first motor drives the first screw and the second screw to rotate. The reverse thread design allows the two slides to move closer or further apart synchronously. The support spacing can be precisely adjusted according to the actual length of the stainless steel profile, which significantly improves the device's adaptability to different specifications of profiles and enhances its practicality.

[0014] 2. The second motor drives the rotating plate to rotate, so that the extension and retraction direction of the fourth electric push rod can be switched to be perpendicular to the pressing direction. The push plate pushes the profile laterally, which can effectively correct the placement position of the profile and ensure that it is in a precise positioning state before welding, thereby improving the accuracy of the welding reference.

[0015] 3. The pressure plate is driven to descend vertically by the third electric actuator, and with the guidance of the guide rod, the end of the profile is stably pressed and fixed, avoiding deviations caused by profile displacement during welding, ensuring welding accuracy, and improving the stability of welding quality.

[0016] 4. The lifting plate is raised and lowered by the first electric actuator, and the second electric actuator, together with the horizontal rail and the first slider, adjusts the horizontal position of the welding head, forming a two-dimensional adjustment in the vertical and horizontal directions. This can flexibly adapt to welding needs at different heights and positions, expanding the application scenarios of the device.

[0017] 5. The vertical rail guides the lifting process of the lifting plate, while the horizontal rail restricts the movement trajectory of the first slider. This dual-guide design effectively reduces swaying during movement, ensuring smooth operation of all components and improving the overall reliability of the device. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] As attached Figure 1-4 An automatic welding and positioning device for stainless steel profiles is shown, comprising a base plate 1, a column 2 on the base plate 1, a top plate 3 supported at the top of the column 2, a first electric push rod 4 mounted on the top plate 3, a lifting plate 5 connected to the telescopic end of the first electric push rod 4, a second electric push rod 8 mounted at one bottom end of the lifting plate 5, a first slider 6 mounted at the end of the second electric push rod 8, a welding head 7 mounted at the bottom of the first slider 6, an adjusting mechanism 10 mounted on the base plate 1, a clamping assembly 11 mounted on the adjusting mechanism 10, and a side push assembly 12 mounted on one side of the clamping assembly 11.

[0025] In practice, the distance adjustment mechanism 10 operates according to the length of the stainless steel profile to adjust the distance between the two slide blocks 1004. Then, the two ends of the stainless steel profile are placed on the corresponding slide blocks 1004. The side push assembly 12 is operated to push and position the stainless steel profile. Then, the two pressing assemblies 11 are used to press and fix the ends of the stainless steel profile, thereby completing the positioning and fixing of the stainless steel profile. Finally, the first electric push rod 4 is extended to raise and lower the lifting plate 5. The second electric push rod 8 is extended and retracted to adjust the position of the first slider 6, thereby adjusting the horizontal position and height of the welding head 7, so that the stainless steel profile after positioning and fixing can be welded.

[0026] A vertical rail 9 is provided on one side of the column 2, and the vertical rail 9 is slidably connected to one end of the lifting plate 5.

[0027] The bottom end of the lifting plate 5 is equipped with a horizontal rail, and the first slider 6 is slidably connected to the horizontal rail.

[0028] In practice, the lifting plate 5 can be raised and lowered by extending and retracting the first electric push rod 4, and is guided by the vertical rail 9 to improve the vertical stability of the lifting. The first slider 6 is slidably installed at the bottom of the horizontal rail, which facilitates the extension and retraction of the second electric push rod 8, guides the movement of the first slider 6, and prevents the first slider 6 from falling.

[0029] The adjusting mechanism 10 includes a first motor 1001, a first screw 1002, a second screw 1003, a slide block 1004, and a slide rail 1005. The first motor 1001 is mounted on the base plate 1. The output end of the first motor 1001 is connected to the first screw 1002. One end of the first screw 1002 is connected to the second screw 1003. The slide block 1004, which is slidably connected to the slide rail 1005, is sleeved on both the first screw 1002 and the second screw 1003.

[0030] In practice, the operation of the first motor 1001 enables the first screw 1002 and the second screw 1003 with opposite threads to rotate synchronously, thereby causing the two slides 1004 to move closer or further apart. This allows the support spacing to be adjusted according to the length of the stainless steel profile, thus improving the practicality of use.

[0031] The side-push assembly 12 includes a second motor 1201, a rotating rod 1202, a rotating plate 1203, a fourth electric push rod 1204, and a push plate 1205. The second motor 1201 is mounted on one side of the slide block 1004. The output end of the second motor 1201 is connected to the rotating rod 1202. The rotating plate 1203 is fixedly connected to the rotating rod 1202. The fourth electric push rod 1204 is mounted on the rotating plate 1203. The push plate 1205 is mounted on the telescopic end of the fourth electric push rod 1204.

[0032] In practice, the second motor 1201 operates, causing the rotating rod 1202 to rotate, which in turn causes the rotating plate 1203 to rotate. This causes the extension and retraction direction of the fourth electric push rod 1204 to be perpendicular to the pressing direction of the pressing assembly 11. The extension of the fourth electric push rod 1204 allows the push plate 1205 to push the stainless steel profile placed on the slide block 1004, thereby straightening and positioning the stainless steel profile.

[0033] The pressure-fixing assembly 11 includes a third electric push rod 1101, a pressure plate 1102, and a guide rod 1103. The third electric push rod 1101 is mounted on an L-shaped bracket provided on one side of the slide block 1004. The pressure plate 1102 is installed at the telescopic end of the third electric push rod 1101. Two guide rods 1103 that are slidably connected to the L-shaped bracket are symmetrically arranged at the top of the pressure plate 1102.

[0034] In practice, by extending the third electric actuator 1101 and guiding it under the guidance of the guide rod 1103, the pressure plate 1102 can be lowered vertically, thereby pressing the stainless steel profile firmly and ensuring that the stainless steel profile is fixed after positioning, thus improving the accuracy of subsequent welding.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
